Chrysanthemum plant named ‘CIDZ0009’

ABSTRACT

A new  Chrysanthemum  plant named ‘CIDZ0009’ particularly distinguished by the large sized decorative inflorescences with pure white ray floret color, medium green foliage, strong and vigorous growth, excellent flowering uniformity, good branching and an 8.5 week flowering response.

Latin name of the genus and species of the plant claimed: Chrysanthemum×morifolium.

Varietal denomination: ‘CIDZ0009’.

BACKGROUND OF THE NEW PLANT

The present invention comprises a new Chrysanthemum, botanically known as Chrysanthemum×morifolium, and hereinafter referred to by the variety name ‘CIDZ0009’.

‘CIDZ0009’ is a product of a planned breeding program. The new cultivar has large sized decorative inflorescences with pure white ray floret color, medium green foliage, strong and vigorous growth, excellent flowering uniformity, good branching and an 8.5 week flowering response.

‘CIDZ0009’ originated from a hybridization made in June 2006 in a controlled breeding environment in Salinas, Calif., USA. The female parent was the proprietary plant designated ‘YB-A6182’, unpatented, with white ray floret color, less vigor, one week faster flowering response, and spoon-type ray florets.

The male parent of ‘CIDZ0009’ was an unpatented, proprietary plant identified as ‘YB-A8041’ with cherry pink ray floret color and a more open-centered inflorescence. The resultant seed was sown in October 2006 in Fort Myers, Fla., USA.

‘CIDZ0009’ was selected as one flowering plant within the progeny of the stated cross in March 2007 in a controlled environment in Fort Myers, Fla., USA.

The first act of asexual reproduction of ‘CIDZ0009’ was accomplished when vegetative cuttings were propagated from the initial selection in June 2007 in a controlled environment in Fort Myers, Fla., USA.

BRIEF SUMMARY OF INVENTION

Horticultural examination of plants grown from cuttings of the plant initiated in June 2007, and continuing thereafter, has demonstrated that the combination of characteristics as herein disclosed for ‘CIDZ0009’ are firmly fixed and are retained through successive generations of asexual reproduction.

‘CIDZ0009’ has not been observed under all possible environmental conditions. The phenotype may vary significantly with variations in environment such as temperature, light intensity and day length.

A Plant Breeder's Right for this cultivar was applied for in Canada on Aug. 17, 2010 (10-7067). ‘CIDZ0009’ has not been made publicly available more than one year prior to the filing of this application.

The following traits have been repeatedly observed and are determined to be basic characteristics of the new variety. The combination of these characteristics distinguishes this Chrysanthemum as a new and distinct variety.

BRIEF DESCRIPTION OF THE PHOTOGRAPHS

The accompanying photographic drawing shows typical inflorescence and foliage characteristics of ‘CIDZ0009’ with colors being as true as possible with an illustration of this type.

The photographic drawing shows in FIG. 1 four flowering potted plants of the new variety, and in FIG. 2 a close-up of the inflorescence.

DETAILED BOTANICAL DESCRIPTION

The plant descriptions, measurements and aforementioned photographs were taken in Gilroy, Calif. in early May 2011 under natural light. These plants were propagated and grown in Nipomo, Calif. and shipped to Gilroy, Calif. for the data collection and photographs. These plants were approximately 11 weeks of age; grown as four plants together in a six inch pot, under greenhouse trial conditions
